Scaffolging plug “POWERDRIVE WALL“ made of pure nylon is used
together with Hüfner eyebolt “EYE“ Ø 12 mm. A special thread
guidance reduces the turn in power of the eye-bolt up to 35 %. A
second thread guidance at the bottom of the plug avoids stretch
forming of the plug and raises the overall pull out results. Up to
21,5 kN in brick MZ12/20 were achieved. Hüfner cover cap “RING“
and “KREUZ“ complete the system.
